2 Claims.

In the loading of freight-carrying trucks, cars, etc., it is customary to stow the load in place rpiece by piece; This entails a corresponding idle period for the truck at the loading platform and cuts down its time-erliciency, and interposes an ulnwanted delay in many instances in special :delivery schedules. In some situations also, Where loading has to be done over -a sidewalk or in an alley-way, prolonged blocking of the space at the loading platform is highly objectionable. It has been proposed to prearrange the load in a box, skid or other type of body so that at the time of loadingit into a truck, freight car or the like, the load is moved not piece by piece but as a unit into the truck or the like and the skid or body withdrawn leaving the load in the truck. In such cases it is important to be able to adjust the height of the skid or body to suitably engage thebed of the truck cr car being loaded since the beds of such trucks are of different heights and by the present invention this is made possible in a manner particularly advantageous.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawings setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which the principle of the invention may be employed.

In said annexed drawings:-

Fig. 1 is a side elevational view of an embodiment of the invention applied to a loading device 35 of the type referred to; Fig. 2 is a similar view showing the device in its discharging position;

Fig. 3 is a rear elevation, on enlarged scale; Figs.

4 and 5 are vertical and transverse sectional details taken on planes substantially indicated by 40 lines IV and V, respectively, Fig. 1; and Fig. 6

is a wiring diagram of the electric control circuits. Fig. 'l is a fragmentary sectional view taken from the plane 'l-l and showing a nut and wrench arrangement which I may employ.

Referring more particularly to the drawings, there is shown a movable loader body or support 2A which may vary somewhat as to its form, but

which is in general a support on which the load may be formed, and which may be open at both ends and provided with sides if desired suitable for assisting in rapid alignment of packages or bundles as stacked into position for the load, and being movable into and out of the vehicle to then be given the load. The bottom of the loader is movable per se in some suitable arrangement so as to allow of its being operated for discharge of the prepared load stacked thereon, and one desirable form of construction for such a movable bottom is a roller or endless belt arrangement, a single belt 4 of width suflicient to extend from side to side of the loader, or a plurality of spaced belts, the endless belt construction being mounted to run over pulley rollers 6, 5, the former being an idler, and the latter positively driven at controlled times as detailed hereinafter. Intermediate rollers for the belt are provided as necessary. By a suitably small diametered pulley or roller I6, the effective bottom of the loader is not unduly elevated above the floor of the car or truck in which the loader is to operate.

iently channel irons.

The track wheels lll are mounted in a bracket under-body portion ll of the loader and are arranged to be driven through suitable gearing by a motor l2 controlled from the controller box I3 which is positioned at a convenient point at the back end of the loader, accessible from the stepboard I 4 of the loader Where the operator can stand for the discharge of the device. While the weight may be so compensated and the track wheels so positioned as to support the device in all of its positions, it is generally desirable to have forward support rollers IB in the supporting under-frame, as adjacent the front post la, and also a pair of running-Wheels Il, carried at the forward end of the loader, and adapted toride onto the oor of the car or truck when the loader is in its forward or projected position therein. Depending upon the balancing of the Weight apportionment, the wheels ll need contact with the fioor of the car or truck only for a portion of the travel of the loader.

The belt drive motor.

Preferably a motor 20 for this is The loader 2
